What to match before buying
- The linked manufacturer sources explicitly list these 179 model codes for HAFCU1.
- The three Samsung filter families are separate cartridges. Identify the cartridge reference and full appliance model before selecting one.
- Technical DA-part aliases are printed alongside the cartridge family in Samsung's US appliance catalogue.
- Exact code, including /AA, is listed in Samsung's cartridge compatibility table.
Find the model and filter codes
- Photograph the rating label inside the refrigerator.
- Keep the complete model code, including any finish, market or service revision suffix.
- Find that exact code in the model list on this page; an unlisted suffix needs its own manufacturer confirmation.
- Compare HAFCU1 with the cartridge specified in the appliance documentation.
- Compare the reference and pack on the final Amazon page; the shopping destination does not establish compatibility.
Other models and cartridge variants
- These sources do not extend compatibility to unlisted model variants or revisions.
- US source coverage does not establish compatibility for another regional model.
